Not personally, but i've got friends that seem to be enjoying it quite a lot.
I stopped touching shooters after BO2. But i like that they're bringing new stuff in the table.
Though, for me the real dealbreaker when it came to these games has always been the campaign. Following an npc while he tells you what you should do is the last thing shooters should aim for...
Also what's the deal with the whole single player in this game? Weren't there rumors of there not being one?
